Simplified installation with Modbus

Combined ultrasonic sensor u[sonic] Modbus for wind direction and wind speed. The Modbus RTU interface simplifies sensor installation and integration into networks. This seawater resistent ultrasonic sensor is perfectly heated and ideal for use under cold climate conditions. The connection of the u[sonic] Modbus is compatible with all meteorology sensors of the Modbus series.

  • No moving measuring elements, no wear
  • Two parameters measurable in one device
  • Intelligent heating, depending on wind speed and direction
  • Easy to install, easy to maintain
